In case you are wondering these numbers are picked quite randomly. Only after it makes itself known does the search start for things associated with it.

Sometimes there is a lot, sometimes not so much. Sixty-four seems to be a well used number so a lot of information below.

If you are into numbers, enjoy.

Sixty-four is the smallest number with exactly seven divisors;

Sixty-four is the lowest positive power of two that is adjacent to neither a Mersenne prime nor a Fermat prime;

Sixty-four is the sum of Euler’s totient function for the first fourteen integers;

Sixty-four is also a dodecagonal number and a centered triangular number;

In base 10, no integer added up to its own digits yields 64, hence it is a self number;

Base64

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.

Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remain intact without modification during transport.

Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML.

Graham’s number

Graham’s number, named after Ronald Graham, is unimaginably larger than other well-known large numbers such as a googol, googolplex, and even larger than Skewes’ number and Moser’s number.

The number gained a degree of popular attention when Martin Gardner described it in the “Mathematical Games” section of Scientific American in November 1977, writing that, “In an unpublished proof, Graham has recently established … a bound so vast that it holds the record for the largest number ever used in a serious mathematical proof.” The 1980 Guinness Book of World Records repeated Gardner’s claim, adding to the popular interest in this number.

Specific integers known to be far larger than Graham’s number have since appeared in many serious mathematical proofs (e.g., in connection with Friedman’s various finite forms of Kruskal’s theorem).

In Computing

64-bit

In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory addresses of 64 bits (eight octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code with 64-bit virtual memory addresses

Commodore 64

The Commodore 64, commonly called C64, CBM 64 (for Commodore Business Machines), or VIC-64, is an 8-bit home computer introduced in January 1982 by Commodore International.

Volume production started in the spring of 1982, with machines being released on to the market in August at a price of US$595.

Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes (65,536 bytes) of RAM, and had favorable sound and graphical specifications when compared to contemporary systems such as the Apple II, at a price that was well below the circa US$ 1200 demanded by Apple.

For a substantial period (1983–1986), the C64 dominated the market with between 30% and 40% share and 2 million units sold per year, outselling the IBM PC compatibles, Apple Inc. computers, and Atari 8-bit family computers.

Sam Tramiel, a later Atari president and the son of Commodore’s founder, said in a 1989 interview “When I was at Commodore we were building 400,000 C64s a month for a couple of years.”

.

Dragon 64

The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer (CoCo), and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana.

The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.

In militaria

HMS Vansittart

HMS Vansittart was an Admiralty modified W class destroyer built for the Royal Navy. She was ordered in January 1918 from William Beardmore & Company with the 13th Order for Destroyers of the Emergency War Program of 1918-19. She was the second Royal Navy ship to carry the name which was first used in 1821 for a hired packet.

.

HMS Beverley (H 64)

Completed in July 1920 as USS Branch (DD 197) for the US Navy, on 8 Oct, 1940 she was transferred to the Royal Navy and renamed HMS Beverley (H 64).

On 9 Apr, 1943, during WWII convoy duty in the North Atlantic, HMS Beverley had been seriously damaged in a collision with the British steam merchant Cairnvalona and had taken station in the rear of the convoy. When it was subsequenty attaced by a German U-Boat, U-188, 30 hours later she was hit by torpedos and sunk. HMS Clover (K 134) (Lt P.H. Grieves, RNR) later picked up five survivors and recovered two bodies, but one of the survivors later died on board.

.

HMS Fencer (D64)

The USS Croatan (CVE-14) (originally AVG-14 then ACV-14) was transferred to the United Kingdom on 20 February 1943 under lend-lease where she served as HMS Fencer (D64). As an anti-submarine warfare carrier, Fencer escorted Atlantic, Russian and African convoys, even participating in a strike on the German battleship Tirpitz before being transferred to the Pacific.

Following World War II, she returned to the United States 21 December 1946, stricken for disposal on 28 January 1947 and sold into merchant service 30 December as Sydney.

The ship went through a series of renamings, first to Roma in 1967, then Galaxy Queen in 1970, Lady Dina in 1972 and finally Caribia in 1973 before being scrapped in Spezia in September 1975.

.

HMS Scorpion (D64)

HMS Scorpion (D64) was a Weapon-class destroyer of the British Royal Navy. Originally named HMS Centaur, the ship was renamed Tomahawk and finally Scorpion (in September 1943) before her launch.

Scorpion was the only Weapon-class ship fitted with the Limbo depth charge mortar rather than the older Squid.

In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II.

.

HMS Theseus (R64)

HMS Theseus (R64) was a Colossus-class light fleet aircraft carrier of the Royal Navy, launched on 6 July 1944.

Theseus was laid down to serve in the Second World War, but was not completed before peace was declared in 1945. She was utilized as a training vessel until the outbreak of the Korean War when she was deployed to Korea, commencing standard carrier operations.

In 1956, Theseus was used as an emergency commando carrier, along with her sister-ship Ocean, during the Suez Crisis. From November to December, helicopters from Theseus transported troops ashore, as well as evacuating wounded soldiers. Compared to her actions during the Korean War, her role at Suez was relatively quiet. The following year she was placed in reserve. She was subsequently broken up at Inverkeithing in 1962.

.

USS Wisconsin (BB-64)

The USS Wisconsin (BB-64), “Wisky” or “WisKy”, is an Iowa-class battleship, the second ship of the United States Navy to be named in honor of the U.S. state of Wisconsin. She was launched on 7 December 1943 (the second anniversary of the Pearl Harbor raid).

During her career, Wisconsin served in the Pacific Theater of World War II, where she shelled Japanese fortifications and screened United States aircraft carriers as they conducted air raids against enemy positions.

During the Korean War, Wisconsin shelled North Korean targets in support of United Nations and South Korean ground operations, after which she was decommissioned.

She was reactivated 1 August 1986, modernised and participated in Operation Desert Storm in January and February 1991.

Wisconsin was last decommissioned in September 1991, having earned a total of six battle stars for service in World War II and Korea, as well as a Navy Unit Commendation for service during the January/February 1991 Gulf War.

She currently functions as a museum ship operated by Nauticus, The National Maritime Center in Norfolk, Virginia. .

.

USS Constellation (CV-64)

The USS Constellation (CV-64), a Kitty Hawk–class supercarrier, was the third ship of the United States Navy to be named in honor of the “new constellation of stars” on the flag of the United States and the only naval vessel ever authorized to display red, white, and blue designation numbers.

One of the fastest ships in the Navy, as proven by her victory during a battlegroup race held in 1985, she was nicknamed “Connie” by her crew and officially as “America’s Flagship”.

She was launched 8 October 1960 and delivered to the Navy 1 October 1961, and commissioned 27 October 1961, with Captain T. J. Walker in command. At that time, she had cost about US$264.5 million. Constellation was the last U.S. aircraft carrier (as of 2010) to be built at a yard other than Newport News Shipbuilding & Drydock Company.

.

USS Gettysburg (CG-64)

The USS Gettysburg (CG-64) is a Ticonderoga-class guided-missile cruiser in the United States Navy, built at the Bath Iron Works in Maine and named for the Battle of Gettysburg during the American Civil War.

With her guided missiles and rapid-fire cannons, she is capable of facing and defeating threats in the air, on the sea, or ashore, and underneath the sea. She also carries two Seahawk LAMPS multi-purpose helicopters, but mainly for anti-submarine warfare (ASW).

She is based in Mayport, Florida.

.

U-64

The first U-64 was a Type U-63 class submarine in the Kaiserliche Marine that served during World War I. She was built in 1916 and served in the Mediterranean Sea.

On 19 March 1917, while on patrol in the Tyrrhenian Sea, U-64 torpedoed and sank the French battleship Danton 30 miles south of Sardinia, with the loss of 296 men. She herself was lost on 17 June 1918.

.

In 1937 another German submarine U-64, a Type IXB U-boat of the Nazi German Kriegsmarine, was ordered in July 1937 and launched in September 1939.

This U-64 had a very short career and sank no enemy vessels. Having left her home port of Wilhelmshaven for her first war patrol on 6 April 1940, she was intercepted by Allied aircraft seven days later off the coast of Norway during the invasion of that country and was sunk by a bomb from a Fairey Swordfish aircraft of HMS Warspite. Of her crew of 46, eight men died and 38 escaped from the sinking submarine.

.

K-64

The K-64 Designation was first given to the first Alfa Class Submarine, launched on April 22, 1969.

In 1972, the submarine suffered a major reactor problem in the form of a leak of liquid metal coolant. The superheated metal solidified on contact with the colder outside air, freezing and damaging internal components of the reactor. She was removed from service and towed to Severodvinsk.

The K-64 designation was again given to a Delta IV class submarine launched on February 2, 1986 as the fourth ship of its class, entered in service in the Russian Northern Fleet. The sub was laid down in December 1982 and was built at Sevmash plant in Severodvinsk.

This ship is still in active service.

.

P-64

P-64 was the designation assigned by the United States Army Air Corps (USAAC) to the North American Aviation NA-68 fighter, an upgraded variant of the NA-50 developed during the late 1930s.

Six NA-68s ordered by the Royal Thai Air Force were seized before export by the US government in 1941, after the Franco-Thai War and growing ties between Thailand and the Empire of Japan. These aircraft were used by the USAAC as unarmed fighter trainers.

Seven NA-50s were purchased by the Peruvian Air Force, which nicknamed it Torito (“Little Bull”). The Peruvian NA-50s subsequently saw action during the Ecuadorian-Peruvian War of 1941.

.

The Grumman G-64/111 Albatross

The Albatross is easily the largest of Grumman’s series of utility amphibians, and was the only one originally developed specifically for military service.

The Albatross resulted from a late 1940s US Navy requirement for a general purpose amphibious transport. The first Albatross prototype flew for the first time on October 24 1947, with more than 400 production HU-16s subsequently delivered to the US Navy, US Coast Guard and 12 other nations. Military Albatross missions included general reconnaissance, maritime patrol, anti submarine warfare (in which role it could be armed with torpedoes and depth charges) and search and rescue.

In the late 1970s, Grumman and major US flying boat operator Resorts International began work on a program to convert the Albatross for civil airline service. The conversion incorporated numerous changes to the basic Albatross, including a 28 seat passenger interior, a galley and provision for a flight attendant, upgraded avionics and other improved systems.

In all only 13 aircraft were converted, 12 for Resorts International, and 1 for Conoco Oil/Pelita which operated from Singapore. Several of these are still active, together with ex military examples.

.

AH-64 Apache

The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew.

Originally, the Apache started life as the Model 77 developed by Hughes Helicopters for the United States Army’s Advanced Attack Helicopter program to replace the AH-1 Cobra, and was first flown on 30 September 1975.

The AH-64 was introduced to U.S. Army service in April 1986.

The AH-64 Apache features a nose-mounted sensor suite for target acquisition and night vision systems; is armed with a 30-millimeter (1.2 in) M230 Chain Gun carried between the main landing gear, under the aircraft’s forward fuselage; and has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has a large amount of systems redundancy to improve combat survivability.

The first production AH-64D Apache Longbow, an upgraded version of the original Apache, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over 1,000 AH-64s have been produced to date.

The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands and Singapore; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. U.S. AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip; both British and U.S. Apaches have seen deployments in Afghanistan and Iraq.

.

Sikorsky S-64 Skycrane

The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter, the civil version of the United States Army’s CH-54 Tarhe. The S-64 Aircrane is the current production version, manufactured by the Erickson Air-Crane company.

Erickson Air-Crane purchased the type certificate and manufacturing rights in 1992 and since that date they have become the manufacturer and world’s largest operator of S-64 Aircranes. The Aircrane can be fitted with a 2,650-gallon (~10,000 litre) fixed retardant tank to assist in the control of bush fires, and it has proved itself admirably in this role.

Erickson is manufacturing new S-64s, as well as remanufacturing existing CH-54s, with each being assigned an individual name, the best-known being “Elvis”, used in fighting fires in Australia alongside “The Incredible Hulk” and “Isabelle”.

Other operators, such as Siller Brothers, have followed with their Sikorsky S-64E, Andy’s Pride. The Erickson S-64E nicknamed “Olga” was used to lift the top section of the CN Tower into place in Toronto, Canada.

The S-64 is the first helicopter built with a rear-facing pilot’s seat—this allows the pilot to watch exactly where the load is being placed as he’s flying the helicopter. The feature came in handy in 1993, when an S-64 removed and replaced the Statue of Freedom from the US Capitol building during a renovation. When transporting a big load like that, the S-64 uses an anti-rotation rigging system that prevents the aircraft from twisting and swaying.

.

T-64

The T-64 is a Soviet main battle tank, introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served tank divisions, while the T-62 supported infantry in motor rifle divisions. Although the T-62 and the famed T-72 would see much wider use and generally more development, it was the T-64 that formed the basis of more modern Soviet tank designs like the T-80.

.

W64 nuclear warhead

The W64 nuclear warhead was the Los Alamos Laboratory’s entry into a brief competition between Lawrence Livermore Laboratory and Los Alamos to design an “enhanced-radiation” nuclear warhead (i.e., a “neutron bomb”) for the United States Army’s MGM-52 Lance tactical surface-to-surface missile.

The Los Alamos design, the W64, was canceled in September 1964 in favor of Livermore’s W63. In November 1966, the W63 was canceled in favor of the W70, the model that finally entered production.

.

L64

The L64 was an intermediate calibre British bullpup layout prototype assault rifle developed in the 1970s. The British Army had considered bullpup designs with intermediate calibre rounds in the 1950s, and officially adopted one of these as .280 British in 1951 in the EM-2 and Taden gun. However, US intransigence during NATO standardization efforts, and Winston Churchill’s interest in standards above all, led to the adoption of the significantly more powerful 7.62×51mm NATO round and the British and Canadian armies adopted the L1A1 SLR, a licensed version of the FN FAL, itself originally designed for the .280.

In the late 1960s a new L64/65 “Individual Weapon” was developed, outwardly similar to the earlier EM-2, but adopted a firing mechanism very similar to ArmaLite’s latest AR-18 design. The first examples were available in 1972.

By 1976, NATO was ready to standardize on a small calibre round, and testing of the various rounds head-to-head started in 1977. As designed, the British round out-performed the standard US 5.56 mm. However Fabrique Nationale’s entry based on the 5.56 mm, the “SS-109″ performed as well as the British cartridge. In the end it was selected largely due to its similarity with existing US ammunition.

The L64 pattern was later developed into the SA80 family of weapons, which entered service with the UK in the 1980s.

.

P-64 Pistol

The P-64 is a Polish 9mm semi-automatic pistol designed to fire the 9x18mm Makarov cartridge. The pistol was developed in the late 1950s at the Institute for Artillery Research, which later became the Military Institute of Armament Technology.

Since 1996, the number 64 has been an abbreviation or slang for Nintendo 64 (though N64 is more common) along with the games Super Mario 64, Mario Kart 64 and more.

64 is the maximum number of strokes in any Chinese character.

Group f/64 was a group of seven 20th century San Francisco photographers who shared a common photographic style characterized by sharp-focused and carefully framed images seen through a particularly Western (U.S.) viewpoint. In part, they formed in opposition to the Pictorialist photographic style that had dominated much of the early 20th century, but moreover they wanted to promote a new Modernist aesthetic that was based on precisely exposed images of natural forms and found objects.

64 is the slang term referring to a 1964 Chevrolet Impala, often configured as a lowrider, a popular subject among early-90’s gangsta rap.

Thanks. The military stuff does seem to dominate these, I guess they are into numbers in a big way. If Erickson were around no doubt he’d find more, but he seems to have fallen off the back of the boat again.
Nice video addition too :)
